Coffee is a fundamental part of our lives. Most of us require at least one or two cups to get us moving in the morning, some a lot more! Since it is such an essential part of our lives, removing coffee stains from our clothing is just as important. To remove coffee stains, mix one egg yolk with warm water. Using a clean, white cloth, blot the mixture into the stain until the stain is removed. Wash the garment as you normally would. If the coffee stain remains, add a couple drops of rubbing alcohol to the egg yolk and water mixture and repeat the steps.
